number of "municipal 'towns, in India, the methods of disposal of town"-wastes like night soil and katchra are highly insanitary and wasteful. The katchra dumping grounds and the night soil trenching grounds have often proved to be dangerous sources of fly breeding. For some years now, the compost method has been recommended as a satisfactory system of disposal of town refuse. It has proved to be of higher sanitary standard and has been responsible for better utilization of the wastes as

Some Observations on Fly Breeding in Compost Trenches *Abstract of the paper communicated to and published by the Agricultural Section of the 32nd Indian Science Congress. The work was conducted under the compost scheme financed partly by the Imperial Council of Agricultural Research.
The usual two types of town wastes, viz. rubbish (katchra) and night-soil, are dealt with separately in their sanitary disposal. In most municipal towns in this province, katchra is stacked in heaps above ground, and near the outskirts of the town. Our observations have shown that it is as much a source of fly nuisance as the night-soil, but very little attention is paid to its sanitary disposa...
متن کاملThe effects of refining steps on Kilka (Clupeonella delicatula) fish oil quality
Kilka fish are known as the main industrial and pelagic species of Iran that are captured abundantly in the southern Caspian Sea. This study was conducted to survey the effectiveness of refinement steps on Kilka (Clupeonella delicatula) crude oil quality and fatty acid profiles. Neutralization, bleaching, winterization and deodorization were performed on crude oil with deodorization done under ...

Background and Objectives: Remaining of crude oil in storage tanks usually results in accumulating oily sludge at the bottom of the tank, which should be treated and disposed of in a suitable manner. The efficiency of in-vessel composting process in removing total petroleum hydrocarbons (TPH) from bottom sludge of crude oil storage tanks was investigated in the present study. Material and me...

متن کاملA Review on Crude Oil Fouling and Mitigation Methods in Pre-heat Trains of Iranian Oil Refineries
Crude oil fouling of the equipment surfaces is a troublesome issue which leads to operating difficulties, economic penalties, increased environmental impacts, and health and safety hazards in petroleum industry. With a rough estimation, a minimum cost of equal to 4 million barrels of oil/year is required to be invested to offset the costs of crude oil fouling in Pre-heat Trains of Iranian oil r...
